Explanation:

Ameoba shows holozoic nutrition which is comprised of ingestion, digestion, absorption, assimilation and Egestion.

Ingestion :

1. Ameoba traps food particles through finger-like projections called a pseudopodia .

2. Pseudopodia present outside its body and helps in taking food along with water.

Digestion:

1. Food vacuoles are made after ingesting the food.

2.Enzymes are released in the food vacuole for digestion.

Absorption :

1.After digestion, nutrients enter the cytoplasm through osmosis.

Assimilation:

1. Nutrients are utilised by the cell for various purposes.

Egestion :

1.Food vacuole goes near the cell membrane to empty its contents outside the cell.

2.This results in expulsion of waste materials from the cell.
